ROBERT. E. BLISS AND GRAYDON o. BLISS, or SYRACUSE, NEW Y SASH.

Specification of Letters Patent.

Patented Dec. 13, 1921.

' .Application filed December 30, 1919. Serial No. 348,367.

To all to from it may concern:

Be it known that we, Roenn'r H. Brass and GRAYDON C. BLiss, citizens ofthe United States, and residing, respectively, at Syracuse, Onondagacounty, State of New York, have invented certain new and useful Improvements in Sashes, of which the following is a specification. u

The object of this invent on is to provide an improved metallicframework construction particularly applicable for use in connectionwith door and window sashes. Many suggestions have heretoiorebeenadvanced for fastening the mullions together at their intersections, andit'is'the particular object of this invention to provide an improvedjoint for the mullions lot the sash whereby these members may-be securedto gether in such manner that the oints w ll have maximum strength andrigidity while at the same time the joints are'simple and convenient toconstruct.

One form of our invention is illustrated in the accompanying drawings inwhich:

Figure 1 is a side view of a portion of a sash showing two crossedmullions jointed together;

Fig. 2 is a top view of the same;

Fig. 3 is a side view of one of the mullions;

Fig. e is a side view of a mullion which crosses the mullion illustratedin Fig. 3 g

Fig; 5 is a top view of the mullion shown in Fig. 1 after having beenbent in the operationof preparing the same to unite with the crossmullion;

Fig; 6 is a similar view but showing the mullion bent in a differentmanner, to re-- ceive the cross mullion;

Fig. 7 is a side view of the same; and

Fig. 8 is a section along the line 8-8 of Fig. 7

We illustrate one joint of a door or window sash, but it will beunderstood that the sash may comprise any number of crossed mullionsdividing the same into the desired number of squares or oblong areas, tosuit the use to which the sash is put. Each of the joints is howeverconstructed in the way illustrated in the drawings and hereinafterdescribed.

The mullion 10, which is preferably of rolled metal and is bendable, issubstantially T shaped, having a web portion 10 and a head portion 11. Adove-tailed notch 12 extends transversely through the head portion, andon one side of this notch the head 11' 1s severed from the web 10 for aconsiderable distance, as indicated by the heavy line 13 in Figs. 1 and7. A small portion 14: of the web is however, left integral with thehead, this portion 11 being do ve tailed as 1llustrated,'and locatednear the free end of the severed portion of the head. The severedportion T of the head of the mullioncomprises a tongue. and will behereinafter referred to as such. The dove-tailed portion 14 which fitsinto the dove-tailed notch in the web 10 constitutes when in said notch,a locking means preventing the free end of the tongue T from bendingupwardly in the plane of the web when "for any reason the sash isstrained, to premit the displace ment of a cross mullion which has beenin s'erted in the notch 12.

This cross mullion 15 is similar to the mullion just described but isnotched in a different manner, as illustrated in Fig. 8, a notch 16extending from the bottom of the web 15 up to the base of the headportion 17 Into this notch 16 the web 10 of the first mullion fits whenthe members are secured together.

In forming a jointthe member 10 is bent in the manner illustrated inFig. 5 or in Figs. 6 and 7. In Fig. 5 the web has been bent and thetongue T has remained in alinement with the unsevered portion of thehead. In Figs. 6 and 7 the tongue T is shown as bent laterally andupwardly, Fig. 7 showing the degree of upward bending. In either case,however, the object of the bending is to provide suflicient spacebetween the end of thetongue T and the other side of the notch 12 topermit the insertion of the crossed mullion 15 into the notch 12. Afterbeing bent as described, and the crossed mullion 15 placed in position,the tongue and web of the mullion 10 are again relatively moved tooriginal position. in which posi tion the dove-tailed member 14 entersthe corresponding dove-tailed notch in the web f and firmly locks thefree end of the tongue will be apparent that modifications of theinvention may be made and we do not limit ourselves to the exact formillustrated.

Having thus described the invention what is claimed as new and desiredto be secured .by Letters Patent is r 1. A sash comprising intersectingmullions, a first mullion having a notch in one edge, and a secondmullion having aportion adapted to fit in said notch, the first mullionhaving a bendable tongue adjacent the notch, the free end of the tongueforming one side of the notch, said tongue being adapted to be bentlaterally to provide space additional to the notch to permit theinsertion of the second mullion into the notch, and to be moved into itsoriginal position after said second mullion has been placed in saidnotch,

with its free end engaging said second mullion, and said tongue andfirst mullion having portions interlocking when the tongue isin itsoriginal position, for the purpose set forth.

2. A sash comprising intersecting mullions, a first mullion having adove-tailed notch in one edge and a second'mullion having a dove'tailedportion to fit said notch, the first mullion having a bendable tongueadjacent the notch, the free end of the tongue forming one side of thenotch, said tongue being adapted to be bent laterally to provide spaceadditional to the notch to permit the insertion of the second mullioninto the notch, and to be moved into its original position after saidsecond mullion has been placed in said notch, with its free end engagingsaid second mullion and said tongue and first mullion having portionsinterlocking when the tongue is in its original positiJn, for thepurpose set forth.

3. A sash comprising intersecting mullions, a first mullion having anotch in one edge, and a second mullion having a portion adapted to fitin said notch, the first mullion having a bendable tongue adjacent thenotch, the free end of the tongue forming one side of the notch, saidtongue being adapted to .be bent laterally to provide space additionalto the notch to permit the insertion of the second mullion into thenotch, and to be moved intoits original position after said secondmullion has been placed in said notch, with its free end engaging saidsecond mul- 11on .and said tongue having a dove-tailed projection andsaid first mullion having a dove-tailed notch adapted to receive saidprojection, wherebythe tongueis locked to the mullion when in itsoriginal position, for

the purpose set forth.

4. A sash comprising intersecting mullions, a first mullion having anotch in one edge, and asecond mullion having a portion adapted to fitinsaid notch, the first mullion having a tongue "adjacent the notch, thefree end of the tongue forming one side of the notch, said tongue andmullion being relatively bendable laterally to provide space additionalto the notch to permit the insertion of the second mullion into thenotch, and to be bent to original position after said second mullion hasbeen placed in said notch, with'the' free end of the tongue "engagingthe second mullion and said tongue and first mullion having portionsinterlocking when in said position, for the purpose set forth.. V
